Filed: 1989-11-17
Abstract: PURPOSE:To obtain an abnormal sound generation prevention device where micro computer is eliminated by transmitting mode information by means of a state setting bus provided in the same IC chip and muting an output based on a signal from the bus. CONSTITUTION:When mode information of the state setting bus changes, it is inputted to a latch circuit 42 through the buffer 41 of a mute circuit. Then, the output of a circuit 42-side changes at the timing of an initial pulse supplied to changed latch circuits 42 and 43, and two signals of different levels are inputted to an EX-OR circuit 44. Consequently, the signal of an H level is outputted from the circuit 44, and is transmitted to a mute time setting circuit 45. Then the signal of an L level is generated in the circuit 45, is transmitted to a gate circuit and the circuit is set to an interrupted state for a setting period. Thus, the occurrence of abnormal sound following the change of mode information can previously be prevented without using the micro computer.

Filed: 1988-11-29
Abstract: PURPOSE:To keep a stable optical frequency interval by generating a 2nd beat signal with a frequency of a beat signal caused between two carrier optical frequencies and a frequency of a reference frequency oscillator, using the signal frequency as an error sign and feeding back the result to a light source of one carrier optical frequency. CONSTITUTION:An electric beat signal SR (1st beat signal) of a frequency corresponding to the optical frequency interval of signal lights L1,L2 radiated from a reference light source 1 and a reference light source 2 is obtained as an output of a photodetector 7. Moreover, a mixer 8 synthesizes the electric beat signal SR of the photodetctor 7 with an output of a reference frequency oscillator 9 oscillating the frequency of the reference electric signal to extract a 2nd beat signal SR0. Then an optical frequency control circuit 10 changes the low frequency electric beat signal SR0 being an error signal into a DC signal S1, which is superimposed onto a bias voltage (current) to apply feedback control to the reference light source 2. Thus, the relatively stable optical frequency interval is controlled.

Title: Motor irregularity detecting apparatus
Inventor: HASHIMOTO YOSHIYUKI
IPC: H02P29/00
Filed: 1998-10-21
Abstract: PROBLEM TO BE SOLVED: To provide a motor irregularity detecting apparatus which can reliably and accurately detect irregularity of motor by detecting irregularity of motor considering a proportional control gain or motor indicating current. SOLUTION: An operation apparatus 3 gives a command current value i* to a motor drive circuit 5 while executing the feedback control to reduce the deviation ε between the actual current value i of motor 1 and command current value i* for the motor 1. The motor drive circuit 5 supplies a voltage V corresponding to the command current value i* to the motor 1. The operation apparatus 3 detects irregularity of motor drive circuit 5 or motor 1. Since a determination value |ε| indicating the feedback control condition is compared with a threshold value which changes depending on a proportional control gain Kp in order to determine existence of irregularity, determination can be made accurately and reliably even if the proportional control gain Kp changes.

Filed: 1986-12-17
Abstract: PURPOSE:To obtain a tracking error signal having no offset by generating a signal corresponding to the phase difference between two signals obtained by ORing the exclusive OR of outputs from two pairs of elements as the tracking error signal. CONSTITUTION:Even if the position of the light spot formed on the light receiving surface of four division type light receiving element 1 is displaced and the amplitudes of the respective outputs from elements 1a-1d become unbalanced, the amplitudes of outputted shaping outputs g-j become constant without altering if the amplitudes of the outputs from the elements 1a-1d are made so large that the peak levels of the respective outputs from buffer amplifiers 2, 3, 5 and 6 exceed the reference voltage of a comparator forming shaping circuit 21-24. And the phase difference between two shaping outputs g-j corresponding to the outputs from two elements 1a-1d arranged in a symmetrical position concerning a straight line beta does not alter in some position of the light spot formed on the light receiving surface. Thus, the phase difference does not occur between the outputs from an exclusive OR circuits 25 and 26 and the occurrence of the offset in the tracking error signal (e) can be prevented.
